I tanned a fox hide after a 6 hour sew job 25 years ago..holy crap I am an old fart... turned out OK (well sort of)- but was not at all like the mink & foxhides we sent in. Some of the guys thought it was great, but I was somewhat disapointed.

Maybe some better stuff to use now, but I would send out for professional tanning.

Shed had a huge elk hide done and it is incredible
